INA bearings use environment: according to site conditions and conditions of use and the environment used to select size, precision, combined with suitable bearing is a prerequisite to ensure that the bearing service life and reliability. 　
　　1, the use of site: tapered roller bearings applied to accommodate radial loads in the radial and axial combined loading, usually with two sets of paired bearings use, mainly in the automotive front and rear wheels, active, differential bevel gear, gear reducer, transmission parts.
　　2, allows speeds: installed properly, lubrication good environment, allowing for bearing limit speed of 0.3-0.5 times times. Under normal circumstances, to 0.2 times the speed limit of the most desirable.
　　3, allowing tilting angle: tapered roller bearings are generally relatively tilt the housing bore axis is not allowed, such as tilt, maximum of 2 '.
　　4, allowing temperatures: under normal load, and with high temperature performance of lubricants and lubrication under adequate conditions, General bearings allow the at-30 degrees centigrade-150 ℃ environment temperature.
　　Second, bearing installation:
　　INA bearing installation must be carried out in a dry, clean environment under the condition of. Prior to installation should carefully check the shaft and housing mating surfaces, convex surface of the shoulder end surface, grooved, and connection quality. All tie in with the surface of the connections must be carefully cleaned and remove the Burr, cast NET sand rough surfaces must, inter alia.
　　INA bearing installation clean gasoline or kerosene before, after drying, and ensure good lubrication, bearing grease lubrication and oil lubrication can also be used. When grease lubrication should use non-anti-oxidation and impurities, Rust prevention, extreme pressure grease for superior performance. Grease filled bearing and bearing box of volume-30%, not too much. Double row tapered roller bearings with sealing structure and water pump bearings good grease filled, users can use directly, no longer subject to cleaning.
　　INA bearing installation, you must exert equal pressure on the circumference of the ring face, ring push, do not use lang the first percussion tools directly bearing faces, in order to avoid damages INA bearings. In the case of less interference, can be pressed at room temperature with a sleeve bearing ring face, using hammer tapping sleeves, rings balanced through the sleeve is pushed. If the mass installation, to be used in hydraulic presses. When pressed, should guarantee the outer ring side face and the shell shoulder end surface, inner ring and shaft shoulder end surface clamping, gaps are not allowed.
　　When interference is large, oil-bath heating or induction heating can be used INA bearing method to install heating temperature range of 80 ° c-100 ° c, the maximum cannot exceed 120 degrees centigrade. At the same time, fastening bearing nut or other appropriate method is applied in order to prevent cooling of the bearing width shrinkage after leaving gaps between ring and shaft shoulder.
SKF single row tapered roller bearings are mounted the final clearance adjustments should be carried out. Clearance values should be used depending on the interference of condition and fits the size specified. If necessary, the test should be carried out. Double row tapered roller bearings and water pump bearings good clearance has been adjusted at the factory, installation without adjustment.
　　INA bearing rotating test shall be performed after installation, first for Rotary shaft or housing, without exception, no load power, low speed operation, and then depending on operation gradually increase the rotation speed and load, and detect noise, vibration and temperature, unusual, should stop and check. Running test after normal delivery.
　　Demolition of three, bearing: INA bearings to be removed when you intend to continue using after, you should use the appropriate removal tool. Demolition of the interference fit rings, on the rally can only be added to the ring, and should never be allowed to pass through the rolling force removal, or rolling elements and raceways were bruised.
